1. A method of reproducing three-dimensional images of an object illuminated by or emitting any of the types of radiation known as x-rays, ultraviolet, visible light, infared, microwaves, particle radiation, inluding the steps of:

  • exposing a radiation blocking element to said radiation;

    establishing a pinhole window in said element through which the radiation is restrictively transmitted onto an imaging surface in a non-focused manner to form a complete image having an intensity pattern dependent on window position;

    imparting scanning movement to said window to produce a series of complete images of said object on the imaging surface of different intensity patterns;

    converting the image-forming radiation impinging on the imaging surface into signal energy;

    converting said signal energy into a transparent image on a viewing screen that is locally variable in transmissivity;

    emitting radiation from a movable emission location on a display surface spaced behind said viewing screen;

    directing said radiation from said movable emission location to said viewing screen; and

    imparting movement to the emission location on said display surface in synchronism with said predetermined scanning movement of the window in said radiation blocking element to reproduce an image of said object on said viewing screen that is observed with parallax.
